Developing XML Schemas
Since XML Schema became a standard, XML Schemas are now ubiquitous within XML applications for the validation of XML data. This course teaches you how to develop XML schemas for use within your applications. This training course covers material required for the IBM Certified XML Developer qualification.
Objectives
- Create simple and complex types in XML Schema
- Extend and restrict existing types
- Use object oriented principles of inheritance, polymorphism, and abstraction in their schema development
- Understand the significance of namespaces in XML Schema
- Use include and import elements within schemas
Prerequisites
- Delegates must be familiar with XML. XML experience can come from the ‘XML Overview’ training course. It is also beneficial to be familiar with object oriented programming principles.
